USB devices freezing Windows XP

By vlucinda ·
About a week ago or so, my computer started freezing whenever I plug in a device to one of my USB ports (I have 3 of them). I have to restart the computer to get it unfrozen. I have an HP Pavilion dv 8000.

I use an iPod shuffle, a webcam and occasionally a flashdrive. I used the flashdrive around the time this issue started, but I don't know if that was the cause.

This is what I've tried so far:

1. Uninstalled USB hardware in device drivers
2. Took battery out, waited 30 minutes, restarted
3. Ran the usbman test listed in a previous discussion of this topic and everything checked out. http://www.usbman.com/WebDrivers/Intel%20USB%20System%20Check/USBREADY.EXE

Thanks for any help!

System restore enabled?

Do a system restore to more than one week ago....

Do you have good anti-virus and anti-spyware? Malware infections can have unpredictable results.

System Restore

by vlucinda In reply to System restore enabled?

I tried system restore (it is enabled) to Dec. 21 and it failed. I tried again and it would only restore the system to Jan.7 (that day's date).

I run a full system scan with Norton Anit-virus every week and nothing has shown up.

I don't know if this could be related or not, but I have had some trouble downloading the last batch of MS updates. As I recall, they were all for Office products, though--nothing specifically for the broader OS.

Powered USB hub

by vlucinda In reply to Also try

Thanks, it's good to know this is an option if I can't get any of the internal fixes to work. I am working as an English teacher in a developing country, so finding one here might be a bit more challenging than at home. not impossible, though.

would also be beneficial to the notebook, less wear and tear. Good luck finding one.

Where on the computer does an external port plug in?

by vlucinda In reply to Having a powerd hub

So, it's not at all dependent on the existing USB ports functioning--they can be completely dead and the external port will work?

I will probably get one, even if my current problem is solved, for the reasons you mention above.

A powered USB Hub plugs into a USB Port

by OH Smeg In reply to Where on the computer doe ...

They are different to standard USB Hubs i the fact that they have their own Power Supply and provide 500 Milliamperes at each USB Socket on them.

What most people do not realize is that you can connect up to 128 USB Devices per USB Port with the use of enough USB Hubs. However if even a fair % of those USB Devices get their power from the USB Port you will so run out of power . If on the other hand every USB Device has it's own Power Source then you don't need any extra power to run things. Because this isn't the case they make Powered USB Hubs to help make up for the shortfall from the Power supplied through the USB Ports.

Do you have any devices that do not get their Power from

by OH Smeg In reply to USB devices freezing Wind ...

The USB Ports? Something like a printer?

Well as you only have Norton's here you should try some Malware Scanners so download something like Malware Bytes

http://www.download.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html?tag=mncol&cdlPid=10995429

Spybot S&amp

http://www.safer-networking.org/en/download/index.html

Install, update and restart the computer in Safe Mode and scan till the system is either clean or you Can Not remove something.

Try again and use a Powered USB Hub this time if it still freezes as it is possible that the USB Ports have been overloaded and when you plug in anything that drains the 5 V DC Rail the system falls over.

If possible also test the USB Devices in another computer and check for correct function.

Everything I have with me goes in the USB ports.

Thanks for the links to the Spybot and Malware Bytes programs. I did a scan yesterday and they picked up some things that my Norton antivirus didn't.

Having re-read your post < edited >

by Jacky Howe In reply to USB devices freezing Wind ...

Don't use you memory stick. Start with your PC first as Oh Smeg has suggested and then use the instructions below to Turn off Autoplay before cleaning the USB drive. It can always be re-enabled by reversing the instructions. Turn off System Restore at the first oportunity and re-enable it when you are finished.
<br>
How To Disable Autorun XP Pro
<br><br>
Go to Start Menu > Run and type gpedit.msc
<br>
Select Administrative Templates > System
<br>
Select ?Turn off Autoplay? from right.
<br>
Set the radio button to Enabled, and change the ?Turn off Autoplay on? to All Drives.
<br><br>
XP Home users will need to make the changes by editing the registry directly. To begin, click Start and then click Run
<br>
Type regedit and click OK. The Registry Editor window will open. Backup the Key before proceeding as it can be used to reverse the proceedure.
<br>
In the left pane, navigate to:
<br>
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.
<br>
With Explorer highlighted right mouse click and select Export. Save the file as autoff.reg. It can be used to restore the Registry later on.
<br>
Again with Explorer highlighted, in the right-pane right click the value NoDriveTypeAutoRun and select Modify from the drop down menu. The base value will be set to Hexadecimal. If not, select Hexadecimal.
<br>
Type 95 and click OK.
<br><br>
After running the above processes you can either use the instructions below or try scannibg the USB with MalwareBytes.
<br>
Open the Command Prompt by typing ?cmd? in the run box. In the command prompt type the drive letter of the USB drive and press enter . Now type dir /w/a and press enter.
<br>
This will display a list of the files in the pen drive. Check whether the following files are there or not
<br><br>
Autorun.inf <br>
Ravmon.exe <br>
New Folder.exe <br>
svchost.exe <br>
Heap41a
<br><br>
or any other exe file which may be suspicious.
<br><br>
If any of the above files are there, then probably the USB drive is infected. In command prompt type attrib -r -a -s -h *.* and press enter. This will remove the Read Only, Archive, System and hidden file attribute from all the files. Now just delete the files using the command del filename. example del Ravmon.exe. Delete all the files that are suspicious. To be on a safer side, just scan the USB drive with an anti virus program to check whether it is free of virus or not. Now remove the drive and plug it again. In most of the cases, the real culprit turns out to be the ?Autorun.inf? file which mostly gets executed when someone clicks Ok in the dialog window which appears above. Thus the infections can spread.
